131.
This is called an INDEPENDENT ASSORTMENT.
The genes are separated from one another and sorted into
different gametes.
Option C is the answer.
151.
The 22 pairs of chromosomes which do not code for gender are
called as AUTOSOMAL chromosomes.
Option C is the answer
161.
XY= Male
XX= Female.
Option B is the answer
171.
The male donates X or Y, so determines the sex.
Option A is the answer.
181.
If a female is a carrier for hemophilia (XXh), her phenotype will
be normal blood clotting
Option B is the answer
191.
The genotype of a male having hemophilia is XhY, this means the X
chromosome
has come from MOTHER.
Option B is the answer.
201.
A female to be hemophilic, she must have both recessive
genotypes.
Her genotype is XhXh which means she got her genes both from
mother and father.
Option C is the answer.

What are alleles? Genes for different traits, such as hair color and eye color Alternative forms of a gene for a single trait, such as blue eyes or brown eyes The locations of genes on a chromosome Recessive forms of a kind of characteristic carried by genes Dominant forms of a kind of characteristic carried by genes In order to have the additional information provided by the location of the centromere in chromosomes, the process of karyotyping uses a chemical...
Name Sex-linked traits are genetic char segments of DNA found on chromosomes that Sex-Linked Traits Senetic characteristics determined by genes located on sex chromosomes. Genies are and on chromosomes that carry information for protein production and that are sponsible for the inheritance of specific traits Genes exist in alternative forms called alleics. or a trail is inherited from each parent Like traits originating from genes on autosomes (non-se chromosomes), sex-linked to omosomes), sex-linked traits are passed from parents to offspring...

Both colors are expressed in heterozygotes calico). If alcat has 2 calico kittens, 1 male black kitten, and I female orange kitten, what is the ty p henotype of the father cat? (Hint: Work backwards & use a Punnett square Remember that not every...
16. So far we have been dealing with alleles found on autosomal chromosomes. These chromosomes contain all the genetic information that is not gender related. As a human, you have 44 autosomal chromosomes (22 pairs → 11 chromosomes from your Mom and 11 chromosomes from your Dad). You also contain a pair of sex chromosomes. These chromosomes contain all the genetic information related to your gender. If you are female, you received an X chromosome from your Mom and an...
In humans, brown (B) eye color is dominant to blue (b) eye color and brown (H) hair color is dominant to red (h) hair color. [Assume single-gene traits] Question: Two individuals, who are both heterozygous for eye and hair color, mate. Which of the following is a correct statement about the phenotype ratios expected for their offspring if the genes are unlinked? A) 9/16 will have brown eyes and red hair B) 9/16 will have blue eyes and red hair...

9. Some (many) traits are polygenic, meaning that multiple genes influence the phenotype. Eye color is polygenic. It actually involves several genes, but there are two that have a major role. Polygenic traits are also incompletely dominant. So assume for eye color that there are two genes, B and C. For each, the dominant allele causes the eye to have more pigment, and be darker The two genes are on different chromosomes, and inherit independently. If an individual was Bb...
Uption 4. The inheritance of hair and eye color is very complicated. Scientists have found approximately 10-20 genes responsible for determining hair and eye color in humans (sheesh - I thought a dihybrid cross with 2 genes was bad...). Although many genes are involved in producing these phenotypes, it does seem that just a few genes play a major role in determining the color of our hair and eyes. The following is a simplified, but still somewhat realistic view of...
